Good Day, I would like some feedaback from track day user on good option for sone brakes and square setup. Before I get flammed I did read a lot on it but everyone has different goals and criterias so its hard to really find the answer I'm looking for. Also take into consideration I have an ls3 engine and m3 rear end (not sure about trailing arm /spindle and suspension) to make things a little more complicated.
My plan is to get Apex ARC-8 17x9 et42 on RS-3 255/40r17. I think I will need a spacer up front and camber plates with -2.5f,-2r to make them fit in without rolling the fenders. I want the 17" mainly for keeping the rubber cost down. The Apex site says the wheel will clear 355mm bbk
I currently have stock brake with pss suspension, my first project will be to instal ptoper ducting and upgrade lines/fluid and pads (not sure which one yet). I will be running two set of pads up front (street/track), so ease of pad replacement is a factor.
I currently have ST-40 on my other car (dsm) and I like them, but i dont like the replacement ring cost (brembo rings are even worst).... I would like to keep the cost of consumable as low as possible.
Idially i would like to fit 355x32mm 1 pieces rotors that are cheap to replace, i dont care about the additional weight compared to 2 pieces rotors. Might use rotors made for other cars with the proper offset if it only needs machinig for the hub and i cand find callipers that will fit.
I dont like the m3 csl "upgrade" as the rotors are expensive and are drilled (prone to cracking) and not the greatest on pad wear.
The porsche brembo option isnt the greatest because if you want the larger rotors(345mm) your stock with the m3 csl again...
6 piston 135i brakes. Not the greatest option from what i have read.
It seems the best option would be the z06 6 pot with oem like rotors but then it prob doesnt clear the 17"
I guess im back with the ST, if i go that rte I would want the larger version made for the m3/z4m (355x32mm)

Would these be hard to fit?
Thanks for your feedback, don't hesitate to highlight other options I have not mentioned.
